The Music Notation Project - article on Isomorphic
InstrumentsThe Music Notation Project is a project which explores alternative music notation systems. Its website
has a page which summarises a number of "Isomorphic" instruments, meaning
instruments whose physical note layout presents musical structure in an
identical or similar appearance of intervals in all transpositions. See
http://musicnotation.org/wiki/instruments/isomorphic-instruments/.

Re-colouring of standard keyboard - The Music Notation ProjectThe Music Notation Project also discusses a re-coloured variant of the standard keyboard - see

between the keys. Note that this layout is NOT the same as the Balanced layout.

one section of this website, but for microtonal music (i.e. with
more than 12 notes per octave) rather than as a generalised replacement
for a standard keyboard.
